Answer 1

Explanation:

Understanding the sense of smell

Understanding how the sense of smell works has been heavily studied in recent years. Smell is an important sense as it can alert us to danger like gas leak, fire or rotten food but also is closely linked to parts of the brain that process emotion and memory. Unpleasant and bad smells actually send pain signals to the brain to warn us of possible danger.

Smell is vital for survival of most humans and animals as it enables them to track food and water, find a mate and even communicate. Although our sense of smell is not as acute as other animals we know that humans are able to detect up to 10,000 different odor molecules.
